As a distinctive resource of Chinese civilization， traditional Chinese medicine （TCM） technology transfer faces significant opportunities under the background of digital and intelligent transformation， while also being constrained by unique challenges such as the complexity of its theoretical system， lengthy industrial chains， and multidimensional policy restrictions， resulting in a "high-value-high-threshold" paradox. At present， TCM technology transfer is deeply trapped in a "threefold reluctance" dilemma， i.e.， unwillingness to transfer， inability to transfer， and lack of capacity to transfer. Specifically， the disconnection between scientific research evaluation systems and market demand leads to low conversion rates of research achievements， unclear ownership and compliance risks suppress innovation incentives， and the absence of professional services intensifies supply-demand mismatches. This article systematically analyzes the specific characteristics of TCM technology transfer and proposes a breakthrough pathway centered on full-chain digital and intelligent transformation. By integrating technologies such as intelligent sorting systems， blockchain-based traceability， and AI diagnostic models， the TCM ecosystem spanning "cultivation-production-service" can be reconstructed. In terms of standardization， promoting the progression from "experience-based data conversion" to "data standardization" and further to "intelligent standardization" is advocated to resolve quality control challenges. For example， a "three-no-one-full" certification system can strengthen quality trust. Policy coordination should focus on optimizing mechanisms for the transformation of scientific and technological achievements， while exploring intellectual property securitization and risk-sharing models to stimulate research momentum. In terms of internationalization， reliance on the Belt and Road Initiative platform to promote the export of geo-authentic medicinal material brands and standards is recommended to build a dual-driven model of "technology plus culture". Looking ahead， through the construction of national-level databases， the cultivation of interdisciplinary talent， and the mutual recognition of international standards， a new paradigm of "scientific intelligent manufacturing" can be formed， providing systematic solutions for the modernization of TCM and global health governance.

OBJECTIVE To evaluate the efficacy and safety of Weiyan Tongluo Granules in treating chronic atrophic gastritis(CAG)and explore its potential mechanisms.METHODS From June 2020 to December 2022,100 CAG patients with spleen defi-ciency and blood stasis syndrome were enrolled and randomly divided into a trial group(n=50)and a control group(n=50)using a random number table.The trial group received Weiyan Tongluo Granules plus a folic acid placebo,while the control group received fo-lic acid tablets plus a traditional Chinese medicine granule placebo.The treatment course for both groups was 24 weeks,with 8 and 10 dropouts in the trial and control groups,respectively.Post-treatment comparisons included OLGA/OLGIM staging reversal rates,low-grade intraepithelial neoplasia regression rate,SSDPRO-CG(Patient-Reported Outcome Scale for Chronic Gastritis in Spleen-Stomach Diseases)scores,TCM syndrome scores,and safety indicators.Serum levels of PG I,PGⅡ,PGR,and G-17 were measured via ELISA before and after treatment.Gastric mucosal p-NF-κB and CDX2 protein expression levels were analyzed by Western blot,while mRNA levels of IL-1β,IL-6,VIL1,and MUC2 were quantified via qPCR.RESULTS After treatment,the trial group showed sig-nificantly higher OLGA and OLGIM stage reversal rates than the control group(P<0.05,P<0.01),though no significant difference was observed in low-grade intraepithelial neoplasia regression.Both groups exhibited significant improvements in physiological domain scores and total SSDPRO-CG scores(P<0.01),with the trial group outperforming the control group in physiological,independence,psychological domains,and total scores(P<0.05,P<0.01).TCM syndrome scores(total and sub-items:gastric distension,pain,poor appetite,bloating)decreased significantly in both groups(P<0.01),while the trial group showed greater reductions in loose stools and dull complexion(P<0.01).After-treatment,the trial group had significantly lower TCM syndrome scores than the control group(P<0.05,P<0.01).Serum PG I,PGⅡ,PGR,G-17,gastric mucosal p-NF-κB,CDX2,and IL-1β,IL-6,VIL1,MUC2 mRNA levels improved significantly in the trial group(P<0.05,P<0.01),while the control group improved only in PGⅡ(P<0.05,P<0.01).The trial group's improvements in these biomarkers surpassed the control group's(P<0.05,P<0.01).No treatment-related adverse events occurred in either group.CONCLUSION Weiyan Tongluo Granules ameliorate gastric mucosal pathology,clinical symptoms,psychological state,and quality of life in CAG patients without significant adverse effects.Its mechanism may involve sup-pressing the NF-κB pathway to reduce IL-1β and IL-6 expression,downregulating CDX2 to inhibit VIL1 and MUC2 transcription,thereby reversing the vicious cycle of inflammation-intestinal metaplasia.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.
